Research reveals that smart watch straps contain persistent toxic chemicals.
A study has found the presence of permanent toxic chemicals in bracelets sold by well-known brands. Interestingly, as the price increases, so does the associated risk.
A recent study has highlighted the presence of perfluorohexanoic acid (PFHxA) in fluoroelastomer straps sold with smartwatches and fitness bands. This finding is based on research conducted by a team of experts and published in a prestigious journal. In the analysis, straps from well-known brands such as Google, Samsung, Apple, Fitbit, and CASETiFY were examined. It has been noted that both Samsung and Apple market fluoroelastomer bands, which mention "benefits" on their digital platforms.
The researchers express concern due to the high concentration of PFHxA that can be readily extracted from the surface of these straps. This is alarming, as smart devices are used beyond daytime activities. As sleep tracking features become common, users tend to wear these straps even while sleeping. The research team warns that using these devices for more than 12 hours a day can facilitate significant transfer of chemicals to the skin, leading to considerable human exposure.
Many of the straps are aimed at sports enthusiasts, implying frequent contact with sweat and increased skin pore openness. Furthermore, the analysis indicates that around 50% of PFHxA exposure may be absorbed through the skin, and over a third may enter the bloodstream. High concentrations of PFHxA have been documented in blood samples, raising questions about the long-term effects of these compounds.
PFHxA belongs to a category of chemical substances known as "forever chemicals," which are notorious for their resistance to environmental degradation and have been present in consumer and industrial products for decades due to their durability against elements like water and oil. However, their negative impact on health is becoming increasingly evident, as they have been linked to various health issues, including several types of cancer.
In the study, the researchers focused on fluoroelastomers, a type of synthetic rubber derived from PFAS, analyzing the presence of fluorine and other harmful chemicals. Interestingly, higher-priced straps showed a greater concentration of these substances compared to more economical ones. Of the 22 straps analyzed, all showed fluorine. Some straps that were not explicitly fluoroelastomer also revealed fluorine levels, suggesting the presence of PFAS. PFHxA was the most common forever chemical, found in nine of the 22 tested straps, with concentrations exceeding those of many cosmetics.
It is suggested that these high concentrations may be related to the use of PFHxA as a surfactant in the manufacturing process of fluoroelastomers. In conclusion, a co-author of the research recommends seeking more affordable straps to minimize exposure to PFHxA and to avoid those containing this substance.
